If you think pancakes are good and free is better, the International House of Pancakes has a deal for you. On Tuesday, March 4, IHOP will be giving out free pancake short stacks in celebration of National Pancake Day, a holiday the company created in 2006.

Just show up at any of the chain’s 1500 or so stores (from 7 a.m. to 10 p.m.) and bring your appetite. The only string attached to your free short stack—and you are limited to just one stack—is a suggested donation to Children’s Miracle Network Hospitals.

Since 2006, IHOP says it has raised $13 million for charity through its National Pancake Day promotions.
